Electrophoretic mobility of human lymphocytes purified by nylon wool columns and spontaneous sheep red blood cells rosetting techniques correlation with immunofluorescence.

Cell electrophoresis allows separation of normal human lymphocytes into two principal groups which are a function of their relative rates of migration. In 42 healthy adults, 19.9% of the lymphocytes have a slower migration rate, and 80.1%, a faster migration rate than the reference speed (1 mum - sec-1 - cm). Two methods are used for the selection of the lymphocytic populations: spontaneous rosetting with sheeps red blood cells, a property of T-lymphocytes, and adherence to nylon wool columns, which preferentially selects B-lymphocytes. The cells which do not form spontaneous rosettes, but adhere to nylon wool columns show mainly slow migration. Cells which do not adhere to nylon columns show a faster migration rate. These findings affirm the T-nature of the rapidly migrating lymphocytes, and the B-nature of the slow-migrating lymphocytes. Results by the immunofluorescence technique confirm this.
